Question

Cooling systems

Lubrication of a non-separable case cooler for 300 rubles. What's better? Try to lubricate or is it easier to buy a new one and not bathe?

Answer 1

New. This is a consumable. And why exactly 300? But not for 200 or 500?

Answer 2

change the cooler and add a dust filter, it will be more useful

Answer 3

Only a replacement.
Lubricate is for those who like to pick unfamiliar details with a screwdriver.
When choosing, carefully read the service life (in hours) and noise.
The price usually reflects the content of these characteristics, although there are "Fashionable" items that do not shine with anything other than a high price.
